To find the unit digit in the product of the numbers 624, 708, 913, and 463,
we can use the fact that the unit digit of a product is the same as the unit digit of each of the factors.
The unit digit of 624 is 4, the unit digit of 708 is 8, the unit digit of 913 is 3, and the unit digit of
463 is 3. Therefore, the unit digit of the product of these numbers is the same as
the unit digit of 4 * 8 * 3 * 3, which is equal to 8.
Therefore, the unit digit in the product (624 * 708 * 913 * 463) is 8.
